` Applicationmedmy 1,1901. serai 110.462,740. (No specimens.)

To all whom it may con/cern:`

Be it known that I, LEOPOLD S. SAMUEL, a

on, which form a part of this specification.

This invention relates to that class of soap cakes represented by the one in my prior patent, No. 549,687, dated November 12, 1895, having receptacles in its opposite sides with matter different from the body of the soap therein. 4

The objects of the present invention are to provide for more easily and readily applying medicaments to soaps, either for laundry or toilet purposes, to enable the'medicated substance to be more firmly attached to the soap, to insure the medicament lasting as long as the soap cake, to provide a construction in which either the medicated soap or plain soap can be used, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved soap cake and in the arrangements and combinations of parts of the same, all' substantiallyas will be hereinafter set forth, and finally embraced in the claim.

of said soap cake/a, I form a perforation b,

which extends entirely through the soap cake. This passage from one side to the other of the soap cake may be formed in any suitable way,

either in molding the soap cakeor afterward while the soap is yet soft, the formation of the opening being in any case facilitated by the fact thatgit extends clear through the soap The perforation or passage b when formed I fill with a medicated vcompound of any desirable' nature, which hardens iII place, vand thus retains its connection with the soap cake forming a central portion c, extending through v curely hold the medicament in place. Where the medicament is particularly liable to shrinkage as compared to the soap, I may form in the Walls of the opening recesses as in Fig. 4, so that abrupt shoulders d are provided to positively hold the block c of medicated mat? ter from slipping out of place.

It will be noted that by the present construction as the soap cake is used the exlposed part of the medicated substance wears away uniformly with the soap cake, and because `the passage or yopening extends clear through .the soap cake the medicated substance will be always exposed to van equal extent. Furthermore, the medicament will not be quickly exhausted, but will las't as long as the soap cake lasts, being as fully exposed in a cake of soap which is nearly used up as in a A new cake.

Obviously other forms and shapesmaybegiven the openings .or passages described without departing from the invention as setforth in the following claim, and I do not wish to be limited to the exact shapesshown.

Having thus described the invention, what In testimony that I claim the foregoing I claim as new is have hereunto set my hand this 31st day of A soa cake having a perforation extend- May, 1901.
